Öğe Comparision of dental arch widths in different types of malocclusions.(2008) Basaran G.; Hamamci N.; Hamamci O.To compare dental arch and alveolar widths of patients with Class III and Class II division 1 malocclusions and those with Class I ideal occlusion. Ninety patients were classified in 3 groups of 30 (15 male and 15 female) according to molar relationship. No subjects had received orthodontic treatment, and in all patients, the primary teeth had completely exfoliated. Dental casts of the 90 subjects were made and photographed with a digital camera on a tripod. Dental cast measurements were taken with a dial caliper to the nearest 0.01 mm. All measurements of all subjects were carried out again 2 weeks later to evaluate the measurement error. Analyses of 1-way analysis of variance demonstrated that (1) there were statistical differences in most of the measurements between the Class I and Class III groups (P>.05) and (2) the Class II division 1 group had differences from other groups (P<.05). This result suggests that transverse discrepancy in Class II division 1 and Class III patients may originate from the maxillary posterior teeth. Maxillary intermolar widths are significantly greatest in Class III, Class I, and Class II division 1 groups, respectively.

For a successful orthodontic treatment the etiology of the malocclusion must be eliminated. A proper diagnosis of the malocclusion and elimination is an essential factor, especially in open bite cases. In the present case, patient was a seven year one month old boy who had a severe open bite with class I molar relationship and tongue thrust. In the anemnesis of the patient, tonsillectomy and adenoidectomy surgery was reported at the age of four. Also, difficulty in the speach was another important finding of the patient. The final outcome of the treatment was a great improvement in function andesthetics. The main reason this patient could be successfully treated nonsurgically was her initial compliance, and the proper therapy options used during this two-phase treatment.Öğe Restoration of posterior edentulous spaces after maxillary molar intrusion with fixed appliances (Case report)(2010) Basaran G.; Ayna E.; Basaran E.G.; Unlu G.This case report includes the mini screw supported intrusion of the extruded teeth due to the absence of its antagonist and fixed prosthetic rehabilitation supported with osseointegrated implants. Four mini-screws with 2 mm diameter and 10 mm length were placed in buccal and palatal regions of extruded molars in both left and right sides. The 4 mm intrusion was achieved with Ni-Ti closed spring and elastomeric chain in each side. After the intrusions of the extruded antagonist molars, dental implants were placed in edentulous areas. After 3 months of healing period, fixed prosthetic restorations were made. As the benefit of orthodontic intrusion of extruded molars, no endodontic treatment was needed in order to gain enough vertical space for prosthetic restoration of antagonist edentulous area and the masticatory function was successfully given to the patient.Öğe TNF-?, IL-1? and IL-8 levels in tooth early levelling movement orthodontic treatment(2010) Kaya F.A.; Hamamci N.; Basaran G.; Dogru M.; Yildirim T.T.During orthodontic treatment, the early response of periodontal tissues to mechanical stress involves several metabolic changes that allow tooth movement. The aim of the present study was to determine tumor necrosis factor alpha (TNF-?), interleukin 1? (IL-1?) and interleukin 8 (IL-8) levels in GCF in tooth early levelling movement orthodontic treatment. Seventeen patients, 8 female and 9 male individuals (aged: 16-20 years; mean 18.2 ± 1.4 years), participated in this study. Each subject underwent a session of professional oral hygiene and received oral hygiene instructions. Three months later, a fixed orthodontic appliance was placed. The patients were seen at baseline and between 1-7 days levelling of the teeth. The concentration of TNF-?, IL-1? and IL-8 were shown in Tables 1. There were statistical differences between the observations at the 1-2 day of levelling for TNF-?, IL-1? and IL-8 (p<.05). Orthodontic forced induces rapid release of the TNF-?, 1L-1? and IL 8 levels during tooth movement in gingival crevicular fluid (GCF). The results of this study support the hypothesis that proinflammatory cytokines play a potent role in bone resorption after the application of orthodontic force in short time.Öğe An unusual case: Neurofibromatosis type 5(2012) Callea M.; Ulku S.Z.B.; Giustini S.; Yavuz I.; Ulku M.M.; Montanari M.; Basaran G.Neurofibromatosis is a disease which includes 5 types in its classification. It has been firstly described by Robert Smith in 1849, but its name comes from the first publication in 1882, in which Von Recklinghausen convinced the scientific and medical world that Neurofibromatosis (NF) was a distinct entity. Cafe-au-lait spots, cutaneous neurofibromas and Lisch nodules are the characteristics of the most common forms. Bilateral acoustic neuromas distinguish the type 2. Type 3, Riccardi type and intestinal type are briefly described. Neurofibromatosis type 5 (NF5) is characterized by cafe-au-lait spots restricted to one area of the body. We report oro-dental phenotype of a patient affected by NF type 5, rare per se and unreported in literature.
